Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery equipment technology, specifically a sand and gravel air-screen separator. Background Technology

[0002] With the significant increase in the production and sales of agricultural products such as tea, the need for impurity removal in the refining and processing stage has become increasingly urgent. During the processing of dried tea leaves, impurities such as sand, soil, iron nails, and grains are easily mixed in, along with tea dust and debris. It is necessary to remove impurities and dust through grading to ensure the quality of tea and meet the market's requirements for refined tea. In existing processing, when using an air separator alone, lighter impurities can be screened to the far outlet receiving funnel, but materials and sand and gravel are still mixed in the near outlet funnel, making it impossible to effectively remove sand. If air separators and sand and gravel screening equipment are set up separately, whether air separators are used first and then sand removal or vice versa, there are problems with large equipment footprint and low processing efficiency, which are difficult to meet the high-efficiency production requirements of tea refining. Therefore, we provide a sand and gravel air separator to solve the above problems. Utility Model Content

[0011] (iii) Beneficial effects: Compared with existing technologies, this sand and gravel air screen separator has the following advantages: I. This sand and gravel air-screen separator integrates the vibrating frame, vibrating motor, and vibrating conveying plate of the vibrating conveying component, and the air separation component's outlet pipe, distributor, and blower with the sealing and protective components' upper cover plate, sealing rubber strip, and dust collection hood into the same equipment frame. This eliminates the need for separate air separation and sand and gravel screening equipment, solving the problems of large footprint, cumbersome processing procedures, and low efficiency associated with traditional separate equipment. It is well-suited to the continuous production needs of tea refining, where a single unit can complete the entire process of "material conveying - air separation and impurity removal - sand and gravel separation." Furthermore, the vibrating conveying plate uses a design where a first and second splicing plate are joined together, forming an air outlet that... The precise alignment of the air ducts, combined with the air guide plate, ensures that the airflow is evenly distributed to the tea materials during transport, preventing incomplete separation caused by excessively strong or weak local airflow. The protruding block above the first splicing plate effectively blocks sand and gravel from flying out of the air outlet, preventing sand and gravel from mixing into the tea. The spring device and vibrating motor work together to fully disperse the materials, reducing the problem of sand and gravel encapsulation caused by tea clumping. It can also simultaneously separate tea fragments and dust. The sand and gravel can fall into the collection trough through the air outlet and then enter the storage frame of the sand and gravel collection mechanism through the discharge port. The tea leaves are moved out in an orderly manner from the left side of the device, avoiding material mixing and further ensuring the purity and separation efficiency of the refined tea.

[0012] II. This sand and gravel air separator, through the cooperation of the upper cover plate, dust suction hood, and sealing rubber strip, completely seals the conveying section of the vibrating conveyor plate, preventing dust from overflowing and polluting the workshop environment during the air separation process. At the same time, the dust suction hood collects residual dust in a timely manner. The closed design of the sand and gravel collection mechanism prevents secondary dust generation during sand and gravel collection, meeting the hygiene standards for tea processing and reducing the harm of dust to the respiratory tract of operators. In addition, the height adjustment device can adjust the tilt angle of the equipment frame according to actual processing needs, adapting to tea materials with different moisture contents and particle sizes. The sand and gravel collection mechanism adopts a pull-out design. The sand and gravel are first stored in the storage frame. When cleaning, simply push the pull plate to disconnect the connecting cylinder from the first through hole, and then pull out the storage frame to complete the cleaning. With the sand and gravel falling path formed by the discharge port and the air outlet, the operator can complete the sand and gravel cleaning without disassembling the equipment or stopping the machine. All components are connected by bolts, making it convenient to replace damaged components later, significantly reducing the difficulty and cost of equipment maintenance. Attached Figure Description

[0017] The vibration motor 5 and the blower 11 in this utility model are common electrical devices in the prior art, and this application will not elaborate on their models or internal structures.

[0018] like Figure 1-6As shown, this utility model provides a technical solution: a sand and gravel air screen separator, including a frame 1 and a blower 11. Two sets of symmetrical height adjustment devices 2 are installed at the bottom of the frame 1. Two sets of symmetrical spring devices 3 are installed in the middle of the frame 1 via a connecting plate. Vibrating frames 4 are fixedly connected above the two sets of spring devices 3 via connecting plates. A vibrating motor 5 is installed on the lower surface of the vibrating frame 4. A collection trough 6 is provided above the vibrating frame 4, and a discharge port 7 is provided at the collection point of the collection trough 6. The discharge port 7 is connected to a sand and gravel collection mechanism 8 via pipe fittings. The sand and gravel collection mechanism 8 is installed on the bottom support frame of the equipment frame 1. A set of equidistant air outlet pipes 9 are provided on the inner bottom wall of the collection trough 6. The bottom ends of each set of air outlet pipes 9 are connected to a pipe divider 10 via pipe fittings. A vibrating conveyor plate 12 is provided on the inner side wall of the vibrating frame 4. The blower 11 is fixedly installed on the support frame at the bottom of the equipment frame 1. The output end of the blower 11 is connected to the inside of the pipe divider 10 via pipe fittings. The upper part of the equipment frame 1... The upper cover plate 13 is bolted to the upper part of the equipment frame 1, and the dust hood 15 is bolted to the upper part of the equipment frame 1. The upper cover plate 13 and the dust hood 15 are sealed to the vibrating frame 4 by a sealing rubber strip 14, so that the conveying section of the vibrating conveyor plate 12 is in a sealed state. The vibrating conveyor plate 12 includes a first splicing plate 1201, which is bolted to the inner wall of the vibrating frame 4. A second splicing plate 1202 is spliced ​​to the right side of the first splicing plate 1201. 02 is fixedly connected to the inner wall of the vibrating frame 4 by bolts. The first splicing plate 1201 and the second splicing plate 1202 are both fixedly connected to the upper surface of the collection trough 6, and an air outlet 1203 is formed between the first splicing plate 1201 and the second splicing plate 1202. The air outlet 1203 is connected to the collection trough 6. A guide plate 1204 is provided on the right side of the bottom plate of the first splicing plate 1201. A protruding block 1205 is provided on the right side of the bottom plate of the first splicing plate 1201 to prevent sand and gravel from passing through the air outlet 1203.

[0019] By integrating the vibrating frame 4, vibrating motor 5, and vibrating conveying plate 12 of the vibrating conveying assembly, the air outlet 9, distributor 10, and blower 11 of the air separation assembly with the upper cover 13, sealing rubber strip 14, and dust hood 15 of the sealing and protective assembly into the same equipment frame 1, there is no need to set up separate air separation equipment and sand and gravel screening equipment. This solves the problems of large footprint, cumbersome processing flow, and low efficiency of traditional separate equipment, and is suitable for the continuous production needs of tea refining. A single piece of equipment can complete the entire process of "material conveying - air separation and impurity removal - sand and gravel separation". At the same time, the vibrating conveying plate 12 adopts the splicing design of the first splicing plate 1201 and the second splicing plate 1202, and the air outlet 1203 formed between the two is precisely connected to the air outlet 9. Correspondingly, the air guide plate 1204 guides the airflow, ensuring that the airflow is evenly distributed on the tea material during transport. This avoids incomplete separation caused by excessively strong or weak local airflow. The protruding block 1205 above the first splicing plate 1201 effectively blocks sand and gravel from flying over the air outlet 1203, preventing sand and gravel from mixing into the tea. The spring device 3, in conjunction with the vibration motor 5, can fully disperse the material, reducing the problem of sand and gravel entanglement caused by tea clumping. It can also simultaneously separate tea fragments and dust. Furthermore, the sand and gravel can fall into the collection trough 6 through the air outlet 1203 and then enter the storage frame 803 of the sand and gravel collection mechanism 8 through the discharge port 7. The tea leaves are orderly removed from the left side of the device, avoiding material mixing and further ensuring the purity and separation efficiency of the refined tea.

[0020] The sand and gravel collection mechanism 8 includes a pull-out frame 801. Two symmetrical mounting brackets 802 are fixedly connected to the outer surface of the pull-out frame 801. The two mounting brackets 802 are fixedly connected to the support frame at the bottom of the equipment frame 1 by bolts. A storage frame 803 is inserted into the inner wall of the pull-out frame 801. A first limiting plate 804 is fixedly connected to the front of the storage frame 803. A first through hole 805 is opened on the upper surface of the pull-out frame 801. Two symmetrical second limiting plates 806 are fixedly connected to the upper surface of the pull-out frame 801. The upper surfaces of the two second limiting plates 806... A fixing plate 810 is fixedly connected to the surface by bolts. A sliding groove is formed between the fixing plate 810 and the two second limiting plates 806. A pull plate 807 is slidably connected inside the sliding groove. A connecting hole 811 is opened on the upper surface of the fixing plate 810. A connecting cylinder 809 is fixedly connected to the inner side wall of the connecting hole 811. The top end of the connecting cylinder 809 is connected to the pipe connected to the discharge port 7. A second through hole 808 is opened on the pull plate 807. The second through hole 808 allows the connecting cylinder 809 to be connected to the first through hole 805 through the sliding of the pull plate 807.

[0021] The upper cover 13, dust hood 15, and sealing rubber strip 14 work together to completely seal the conveying section of the vibrating conveyor plate 12, preventing dust from overflowing and polluting the workshop environment during the air separation process. At the same time, the dust hood 15 collects residual dust in a timely manner. The closed design of the sand and gravel collection mechanism 8 can prevent secondary dust generation during sand and gravel collection, which meets the hygiene standards for tea processing and reduces the harm of dust to the respiratory tract of operators. In addition, the height adjustment device 2 can adjust the tilt angle of the equipment frame 1 according to the actual processing needs, adapting to tea materials with different moisture content and particle size. The sand and gravel collection mechanism 8 adopts a pull-out design. The sand and gravel are first stored in the storage frame 803. When cleaning, simply push the pull plate 807 to disconnect the connection between the connecting cylinder 809 and the first through hole 805, and then pull out the storage frame 803 to complete the cleaning. With the sand and gravel falling path formed by the discharge port 7 and the air outlet 1203, the operator can complete the sand and gravel cleaning without disassembling the equipment or stopping the machine. All parts are connected by bolts, making it convenient to replace damaged parts later, significantly reducing the difficulty and cost of equipment maintenance.

[0022] Working principle: Before starting the equipment, the tilt angle of the equipment frame 1 is adjusted by the height adjustment device 2 to ensure that the vibrating conveyor plate 12 is at a suitable conveying slope; then the blower 11 and the vibrating motor 5 are started. The airflow generated by the blower 11 is evenly distributed to each group of air outlet pipes 9 through the distributor 10. The vibrating motor 5 drives the vibrating frame 4 to vibrate at high frequency and low amplitude under the support of the spring device 3. At the same time, the sealed space formed by the upper cover plate 13 and the sealing rubber strip 14 begins to be in a negative pressure state. With the dust extraction effect of the dust suction hood 15, it prepares for subsequent separation; tea leaves and hair The tea material is fed into the inlet of the vibrating conveyor plate 12. Under the vibration of the vibrating frame 4, the material moves to the left side of the device along the length of the vibrating conveyor plate 12. During the movement, the material is fully dispersed by the vibration to avoid clumping. At the same time, the air guide plate 1204 on the first splicing plate 1201 guides the airflow blown out of the air duct 9 to flow obliquely upward along the material conveying direction, initially lifting the light dust and tea fragments in the material, laying the foundation for subsequent air separation. When the material moves to the air outlet formed by the first splicing plate 1201 and the second splicing plate 1202, At point 1203, the airflow intensity from the outlet duct 9 reaches its peak: light impurities in the tea leaves, due to their light weight, are blown towards the upper part of the sealed space by the airflow and are drawn away and collected by the negative pressure airflow of the dust collection hood 15; heavy impurities such as sand and clods of soil, due to their large weight, cannot be lifted by the airflow and slide along the surface of the vibrating conveyor plate 12 under the action of vibration. At this time, the protruding block 1205 above the first splicing plate 1201 can effectively prevent sand and gravel from flying over the outlet 1203, avoiding sand and gravel from mixing into the tea leaves. Finally, under the guidance of vibration, the sand and gravel fall from the outlet 1203 into the interior of the collection trough 6. The tea leaves enter the sand and gravel collection mechanism 8 through the discharge port 7. After separation, the pure tea leaves continue to move to the left side of the device along the vibrating conveyor plate 12 and are finally removed from the discharge port on the left side of the device, thus completing the collection of the tea leaves. The sand and gravel first fall into the storage frame 803 of the sand and gravel collection mechanism 8. When the sand and gravel accumulate to a certain amount, the operator can push the pull plate 807 to disconnect the connecting cylinder 809 from the first through hole 805, so as to prevent the sand and gravel from continuing to enter the storage frame 803. Then, the storage frame 803 can be pulled out to complete the sand and gravel cleaning. The cleaning process does not require stopping the machine and does not affect continuous production.
